Tania Bruguera, a Cuban artist based in New York who was arrested in December in Havana, where she planned to stage an open-mike performance to ask citizens to speak about their visions for Cuba, said Wednesday that she had not been able to find a lawyer willing to defend her and that prosecutors had been given 60 more days to decide whether to charge her. The charges being considered include inciting public disorder. She has been released, but her passport has been confiscated. She said six lawyers had refused to represent her because they believed that her case was a lost cause or feared that defending her might hurt their careers.
